scan results depend on logfile mode???

[Béla Szekeres (pókusz) <pokusz () gmail com>]

Hi all,


I have a weird problem with nmap which is driving me mad. I'm running nmap
7.01 on Kali 2.0.

I have a server with 2 SSL ports, both ports are configured identically,
OpenSSL can connect to both ports. If I run nmap to scan the server, the
results depend on the logfile mode...

=================
root@kali:~# nmap -Pn -sV -p3550,3562 -oN  - pi196
# Nmap 7.01 scan initiated Sat Dec 19 20:12:55 2015 as: nmap -Pn -sV
-p3550,3562 -oN - pi196
Nmap scan report for pi196 (xxx)
Host is up (0.0042s latency).
PORT      STATE SERVICE     VERSION
3550/tcp open  ssl/unknown
3562/tcp open  ssl/unknown

# Nmap 7.01 scan initiated Sat Dec 19 20:13:23 2015 as: nmap -Pn -sV

# Nmap done at Sat Dec 19 20:13:46 2015 -- 1 IP address (1 host up) scanned

=================

I compared the packet trace of both scans and I see only minimal
differences. Tried to recompile the source but the results are the same.

Any ideas?

Best regards,
